Abstract: 1450169 Method of milking E M PHILLIPS 14 Sept 1973 43381/73 Heading AIM A method of milking cows comprising the application to cow's teats a pulsation having two or more patterns of vacuum/air phase, at least two of said patterns being different, the patterns being supplied successively to form the pulsation.  A preferred pulsation comprises an increasing vacuum phase a, a maximum vacuum phase a', a decreasing vacuum phase b (not down to atmosphere), an increasing vacuum phase c, a second maximum vacuum phase a", a decreasing vacuum phase d (down to atmosphere) and a comfort phase e. The pulsation has a duration of 3 secs with the comfort phase e of about 1 sec. A pulsation similar to that of Fig. 3 can be produced by providing a driven cam wheel 11 in a master pulsator (Fig. 6) with successive dwells and raised cams 21 so as to alternately connect the output 24 to atmosphere and a vacuum source, and either restrictions 29, 30 are provided in the output 24 and air inlet 27, or restrictions are associated with the slave pulsators. The method may also be carried out by a normal 50:50 or 40:60 vacuum/air pulsator connected to a flutter valve which on each air impulse changes the size of the restriction in line with the outlet of the pulsator. In further alternative embodiments, pulses are transmitted from a cam-wheel to electric slave pulsators via cam actuated switches, and square wave pulsations are produced by electronic capacitors, restrictions again being provided in the slave pulsators.

Abstract: 1,058,718. Bags; opening bags for filling; cartons. KORSN S G.m.b.H. Nov. 8, 1963 [Nov. 13, 1962], No. 44115/63. Headings B8C, B8K and B8P. A bag, or carton, Fig. 15, has a bellows fold 24 in its base which, when the bag is opened, forms a flat bottom with triangular pockets 39 extending up opposite edges 38 of the bag. In one embodiment the bags are formed from tube pieces, Fig. 3, with bellows folds at each side, closed at either end by folding and pasting down flaps 26. If the tube is lined with suitable material it may be closed by heat seals before folding in flaps 26. In an alternative form flaps 26 are absent and the tube ends are closed by separate tapes pasted on. The entirely closed bag formed as above may have a hose inserted in one of its folded ends to produce a valve bag. Alternatively the tube is cut longitudinally into two open-ended bags which are expanded by inserting contents, or by separating the sides by suction nozzles 41, Fig. 12, and inserting linked plates 42, 43, to flatten the bottom, Fig. 13. To facilitate opening the bag it is folded as in Fig. 14 after the triangular pockets 39 have been glued. Slits 44 produce flaps 45-48, Fig. 15, when the bag is expanded. The bag may be single or multiply, and one of the plies may have a coating of heat sealing material. In a further method open-ended bags are produced from a tube open along one longitudinal edge and having a bellows fold along the other.

Title: Control circuit for tape drive mechanism
IPC: G06K13/20
Filed: 1962-11-23
Abstract: 992, 521. Tape drive control circuits. OMNITRONICS Inc. Nov. 23, 1962 [Dec. 7, 1961], No. 44458/62. Heading G5R. [Also in Division H3] A control circuit 10 for controlling the drive and brake in a photoelectric tape reader has the drive capstan and brake circuits connected to emitter followers which are connected into opposite sides of a bi-stable circuit (see Division H3), so that when this circuit is active the capstan drive and brake cannot be applied simultaneously. A switching arrangement 12 allows the various control functions to be exercised. The power switch 20 controls the supply to all power inputs to the circuit. Activation of the start/stop button 23 applies a pulse to the bi-stable circuit to change its condition, and operation of the load/tape-ready switch in the load tape position disables both the capstan and brake drives, whilst in the ready position applies a positive pulse to the base of transistor T1 in the bi-stable circuit to ensure that this is switched off and the brake drive is applied. Electrical inputs can alternatively be applied at the terminals 17-19 for automatic operation of the control circuit. An inhibit output circuit 16 may be included, which applies an inhibiting output to a tape reader (for example) whenever the capstan drive circuit is inoperative. This ensures that read out is not obtained when the tape is being threaded into the reader before it comes under the control of the drive.
